The junior U.S. senator from New York and leaders of the LGBT community from New York City are set to meet on Sunday to discuss efforts to advance pro-LGBT federal bills in the wake of the latest court ruling against the Defense of Marriage Act.

According to a statement from her office, Sen. Kirsten Gillibrand (D-N.Y.) is scheduled to meet at the Gay Men’s Health Crisis with other public officials, including Rep. Jerrold Nadler (D-N.Y.) and lesbian New York City Council Speaker Christine Quinn. The meeting will occur days after the U.S. Second Circuit Court of Appeals, which is located in New York City, issued a decision declaring DOMA unconstitutional.

Krishna Stone, a GMHC spokesperson, said the clinic’s CEO, Marjorie Hill, will welcome everyone to the event and Gillibrand will speak. A question-and-answer session is set to follow. The meeting is set to begin at 1:45 pm and will take place at the clinic, which is located at 446 West 33rd St. The meeting isn’t open to the public.

In the House, Nadler is the chief sponsor of the Respect for Marriage Act, legislation that would repeal DOMA. Gillibrand is an original co-sponsor of companion legislation in the Senate. The bill is unlikely to become law as long as Republicans retain control of the House.
